New poster here, registered to try and find out some information. My father was given a 1955 Royal Enfield Clipper a few years ago, with the idea to restore it and get it up and running one day. He's never got round to doing this however, and now we've listed it on ebay, with no real idea on its value or anything. We were quite shocked to see that within a few hours of the listing being placed the price shot up to £330. I was hoping anyone here could assist me in giving me a rough valuation and any other information on the bike, by having a quick look at the listing, if that's at all possible? The URL is:

The engine is seized and it is really a complete restoration project, but it seems there is quite a demand for it, as we have many people watching the auction at this early stage.

Many thanks in advance!
